For Video encoding:
configure interface cable-downstream 14/4 cable attribute-mask value 0x80000002
configure interface cable-downstream 14/5 cable attribute-mask value 0x80000002
configure interface cable-downstream 14/6 cable attribute-mask value 0x80000002
configure interface cable-downstream 14/7 cable attribute-mask value 0x80000002
For video downstreams (14/4 -14/7), you can disable primary-capable so that legacy modems do not use them by entering:
configure interface cable-downstream 14/4 shutdown
configure interface cable-downstream 14/5 shutdown
configure interface cable-downstream 14/6 shutdown
configure interface cable-downstream 14/7 shutdown
configure interface cable-downstream 14/4 cable primary-capable no
configure interface cable-downstream 14/5 cable primary-capable no
configure interface cable-downstream 14/6 cable primary-capable no
configure interface cable-downstream 14/7 cable primary-capable no
configure interface cable-downstream 14/4 shutdown no
configure interface cable-downstream 14/5 shutdown no
configure interface cable-downstream 14/6 shutdown no
configure interface cable-downstream 14/7 shutdown no
Configure QoS Groups
Creating a QoS Group includes configuring Service Class Names (SCNs) with the required attribute mask to match the video
attribute and channel attribute, configuring an entry of the Multicast Group QoS (GQC) table, and configuring the Multicast
QoS Groups (GC) and assigning to the GQC ID.
 To Create QoS Groups for Different Devices
The following is an example of how to create from one to four different QoS groups with different max-rates for the
various devices on which the video will be used. It also provides an example of having session ranges.
1. If only one group configuration is required, enter these commands:
configure qos-sc name video-3d max-tr-rate 12000000 required-attr-mask-value 0x80000002 dir 1
configure cable multicast group-qos 1 scn video-3d
configure cable multicast qos group 1 group-qos 1 session-range 235.1.1.1/24 source 0.0.0.0/24
2. To configure additional QoS groups (three groups in this case), enter the following commands:
configure qos-sc name video-hd max-tr-rate 8000000 required-attr-mask-value 0x80000002 dir 1
priority 3
configure cable multicast group-qos 2 scn video-hd
configure cable multicast qos group 2 group-qos 2 session-range 236.1.1.1/24 source 0.0.0.0/24
configure qos-sc name video-pc max-tr-rate 3000000 required-attr-mask-value 0x80000002 dir 1
priority 3
